ABOUT BNCT

BNCTの原理

  Boron Neutron capture therapy (BNCT) is radiation therapeutics for treating locally tumors without major operation.
A drug containing boron (10B, the mass number is 10), which is easy to be incorporated into a cancer tissue, is administered to a patient. When thermal neutrons are irradiated into the patient, the nuclear reactions of 10B are caused as follows:

  10B + n → α + 7Li

The α-rays (4He) and the lithium nuclei (7Li), which are released from the 10B, kill cancer cells effectively. Since the ranges of the α-rays and the lithium nuclei correspond approximately to the size of one cell. Therefore, only cells containing boron are killed, and the damage effects of surrounding normal cells are hardly caused.

Most of BNCT treatment results so far have been performed at research nuclear reactors as the sources of thermal neutrons. In recent years, the developments of the next accelerator based neutron sources for the BNCT are underway worldwide.

  We develop the accelerator based neutron source for the BNCT with a liquid lithium target technology.

A feasibility design study on a neutron spectrometer for BNCT (Boron Neutron Capture Therapy)

  Neutrons generated by accelerators have various energy spectra. Especially, the neutron spectrum in the epithermal region is important in BNCT facility. However, there are a few measurement methods for the neutron spectrum.

We have studied a new neutron spectrometer with a liquid moderator, which can estimate more accurate neutron spectrum by using an unfolding technique.

Study on measuring device arrangement of array-type CdTe detector for BNCT-SPECT

  We study a SPECT system for the BNCT, named “BNCT-SPECT”. This is a three dimensional imaging device to monitor the local BNCT dose (the treatment effect) around the tumor in real time. The principle of the BNCT-SPECT is shown in Fig. 1. The boron neutron capture reaction is expressed as follows.

 10B + n → a + 7Li + 2.79 MeV (6.1%)
  → a + 7Li?+ 2.31 MeV + 'Y (478 keV) (93.9%)

94% of residual 7Li is in the ?rst excited state, i.e., 7Li*. 7Li* decays in its half-life of 10?14 s and subsequently emits a 478 keV gamma-ray through the transition from the ?rst excited state to the ground state. We have developed the BNCT-SPECT to measure the intensity 3-D distribution of 478 keV gamma-rays from the tumor. We have investigated the feasibility of the BNCT-SPECT system by simulations with MCNP5. The BNCT system was composed of an array-type CdTe detector, a collimator, shielding blocks, and the walls of an irradiation room.

BNCT-SPECTの原理

Fusion neutron engineering (fusion neutronics)

  OKTAVIAN was built at Osaka University and has been operated since 1981 as an intense deuterium-tritium (D-T) neutron source at 1.5-ns pulses of 103 D-T neutron/pulse or as the maximum continuous neutron source of 3×1012 D-T neutron/s. This facility has been devoted mainly to studies on fusion neutron-related subjects by many researchers and has also served for international collaborations. OKTAVIAN consists of a high-current deuteron beam accelerator for D-T neutron production. Many fusion neutronics experiments have been carried out for the fundamental study of D-T fusion neutron transport characteristics. They have served to improve the evaluated nuclear data files and to test the calculation methods for fusion reactor designs.
